To all whom t may concern.

Be it known that l. MARCUS PHiLLIrs, a citizen of the United Stat-es, residing at Chicago, in the county of Cook and State of lllinois, have invented new and useful Improvements in Catamaran-Propelling lilechanism, ot which the `tollowing is a specification, reference being had to the accompanying drawings, forming a part thereof.

rl`his application is a division of my application on catamaran, Ser. No. 628,658, tiled May 22, 1911.

The purpose of this invention is to provide an improved hand power motor for use in pleasure craft andfparticularly adapted to be mounted upon a catamaran as illustrated.

lt consists ot the features and elements described and shown in the drawings as indicated in the claims.

ln the drawings z-l `igure l is a top plan view of the motor, showing it mounted on the catamaran which it is employed to propel. Fig. is avertical section taken as indient Y :l at line 2-2 on Fig. l, being an enn lai-ged detail of certain parts of the motor.

, 23 is a section taken as indicated at line CJI 2l-3 on Fig. Q. Fig. is a detail of the swiveled tule-ruin block for the motor lever. Fig. 5 a section taken as indicated at line 5-5 on Fig. 4. llig. t5 is a detail plan view of the adjustable connection bett-veen the motor lever and the connecting rod. Fig. 7 is a section taken as indicated at line 7-7 on Fig. G.

The catamaran shown in Fig. lis more fully illustrated in my co-pending applica- -tion, Serial Number 628,658. Briefly ity consists of a pair orP boat hulls, A, A, connected together by laterally extending flexible conplings, B. ln addition to the flexible couplings, B, there is provided near the middle of the length of the craft a connector' or tie rod, C, ot somewhat heavier material than the couplings, l, but nevertheless sutiiciently flexible to bend readily to accommodate itseltl to any relativerinovement of the hulls. Upon this cross tie, C, is mounted the propeller shaft bearing and the motor, the latter being adapted :tor operation hy hand power. The casting, l, which contains a bushing, la, suitable to serve asa journal bearing for the propeller shaft, 2, is also formed with a lug, l", and a cap, 1, theretor, by which the casting is secured to the cross tie, C, in such a manner as yto permit its being rocked about the tie rod in a vertical plane. The upper side ot the casting, l, is formed with a journal cup, 1d, carrying a journal bushing, le, ,secured therein by one or moreset screws, lf. Into this cu jeX- tends the short stud axle, 3, of the driving gear, 3, of the motor; a flange, 8h, at the lower end ot the axle is engaged by the bush# ing, le, and the driving gear is thus prevented from coming out ot' its bearing. In order to obtain this arrangement, the bushing must be inserted into the cup, 1d,`with the axle, having been previously applied thereto; such application would 'be accomplished by splitting the bushing, as indicated at, 1g, in Fig. 3, and spreading it sutciently to embrace the axle, 8a, after which, since it would be of comparatively soft material, itcould be pressed snugly about the axle and inserted into the cup, 1d, into which it 4would then be secured by the set screws, 1f. The journal cup, ld, is also provided with a grease cup, l, for supplying lubricant to this principal bearing of the motor.

lligidly secured to the shaft, 2, is thedriven gear. 4, meshing with the driving gear, 3; and upon the extreme end ofthe shaft there is mounted a fly Wheel, 5, keyed thereto by a screw, 5a, set into the end of the shaft so as to engage both the shaft and the hub of the fly Wheeh The fly wheel is so cupped or hollowed out as to completely contain the driven gear, 4, Within the limits otl its extent along the axis of the shaft. This design not only affords compactriess of arrangement,but as may be noted by a consideration of the plan View of Fig. 1, it constitutes the rim of the fly wheel a guard for the intermeshing gears, 3 and 4, since with the directional relations as indicated by the arrows on said ligure, it is evident that it the hand or clothing of a passenger should be engaged by the driving wheel, 3, and carried toward the point Where it enters the hollow of the ily wheel t3, it would tend to be carried away fromJ this oint and out of danger, by the direction o rotation of the y wheel. The fly wheel also Serves es e hood te protect; the'v gear, e, from. rain, and
